gas

[48gmc]

have a 48 gmc with a rochester 1 barrel...started yesterday ran for awhile the guit, would not start back up...looking at my glass filter on the gas line, had little gas in it, would keep cranking but will not fill up glass, took top of carb off, the gas was probably 3/8 from top of carb. i let it sit over night today it did the same thing. i have a beer keg in back, rubber line running to pump, my new one, then to carb, floats adjusted according to specs. i am learning and getting frustrated, any info would be great.
